For his 1923 biblical epic THE TEN COMMANDMENTS, director Cecil B. DeMille re-created ancient Egypt on the central California coast with one of the biggest movie sets of the silent era, which was buried on location in Guadalupe-Nipomo Dunes after the film was completed. And there it lay, forgotten, for the next 60 years.... the "lost city of Cecil B. DeMille." In 1983, a group of determined film buffs -- inspired by a cryptic clue in DeMille's posthumously published Autobiography -- located the remains of the set. Director Peter Brosnan’s 30-year quest to unearth the site - and, through numerous interviews, its secrets - makes for one of the most fascinating behind-the-scenes documentaries ever. “For anyone who cares about Hollywood history - or, for that matter, California history - THE LOST CITY OF CECIL B. DEMILLE is an irresistible detective story, told with a sense of wonder, a sense of humor and a mild exasperation over the ‘permit people,’ as Brosnan wryly calls them.” - Sheri Linden, The Hollywood Reporter.
